Hosta x hybrida 'Hirao Tet'

The Story

Plant Bio

Hostas are clump-forming herbaceous perennials, primarily grown for their decorative foliage. They are native to northeast Asia and thrive in shady conditions, producing spikes of lily-like, bell-shaped flowers in summer.

A tetraploid sport of 'Hirao No. 1', this cultivar is prized for its excellent substance. It forms a medium-sized mound of thick, heart-shaped, heavily corrugated, blue-green leaves. Pale lavender, bell-shaped flowers appear in mid-summer on tall scapes.

Practical UsesSuppresses weeds and prevents soil erosion in shaded areas.
